clock signal
the disturbance amplitude that can be compensated for by a differential analog input
the average power that can be dissipated in the regen circuit
internal count pulses, 1 pulse = 1/2
regulates the difference between the current setpoint and the actual current to 0.
Output: power-output voltage
rectified and smoothed power voltage
removal of the ENABLE signal (0V or open)
electrically erasable memory in the servo amplifier, data that are stored in the
EEPROM are not lost if the auxiliary voltage is switched off
the enable signal for the servo amplifier (+24V)
electrically conductive connection between a phase and PE
maximal value for the speed normalization at ±10V
a special way of representing binary numbers
a brake in the motor, that can only be applied when the motor is at standstill
monitoring of the r.m.s. current that is actually drawn
position indication through 2 signals with a 90° phase difference, not an absolute
position output
the r.m.s. value of the pulse current
the r.m.s. value of a steady current
proportional gain of a control loop
to limit the range of movement of the machine; implemented as an n.c. (break)
contact
the total assembly of parts or devices that are connected together, of which at least
one is movable
output of an analog measurement
a packet of data containing all the position parameters that are required for a motion
task
a machine with several independent drive axes
optical connection between two electrically independent systems
a control loop that has purely proportional response
compensation for the lag between the electromagnetic and the magnetic field in the
motor
control loop with proportional, integral and differential response
filter time constant for the speed controller output
regulates the difference between the position setpoint and the actual position to 0.
Output: speed setpoint
the maximum power that can be handled by the regen circuit
volatile memory in the servo amplifier. Data that are stored in the RAM are lost when
the auxiliary voltage is switched off.
converts superfluous (regenerative) energy that is fed back by the motor, during
braking, into heat in the regen resistor.
new start of the microprocessor
operating with a periodic change of direction
incremental position output
an instrument for controlling the torque, speed and position of a servomotor
here: electrically conductive connection between two phases
regulates the difference between the speed setpoint SW and the actual speed to 0.
Output: current setpoint
cyclically absolute, serial position output
limiting of the rate of change of the speed setpoint value
a voltage proportional to the actual speed
filter time constant in the speed feedback of the control loop
integral component of the control loop
is produced by incremental encoders, once per turn, used to zero the machine
